Hey all:
I'm back with a follow up question on the topic of substitution in
Sage. How can i work the following example? I have an expression
that involves the derivative of a function, and into that expression i
want to substitute the value of the derivative. Simple, eh? I tried

Thanks for the explanation. It does work in server 2.

Sweet! Thanks, Mike.

This is bec
I have written an animation which runs fine in SAGE on my PC.
However, when I run the same script on Milnix.org server, I got an
error message:
sh: convert: command not found
what's the problem? any help?
Thanks in advance

Now, with the above in mind, how do you write a function to evaluate
that sine limit given a variable from the user? We know the following
does not work.
sage: var('x')
x
sage: def limmy(w):
: return limit(sin(w)/w,w=0)
sage: limmy(x)
sin(x)/x
More generally, how do you execute function

Here's an example:
sage: v = vector(CDF,[1..10]); v
(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0
Hi all!
Does anyone know where to find guide or example how to use Fourier
transform and inverse Fourier transform in sage?
Thanks.

It's possible somebody might find this useful:
sage: FormalSum
This looks a bit like an additive version of what we already do with
factorizations. I wonder if you could clever use the factorization
class for it?

PS I didn't really mean to suggest that you were stuck on the
mathematics of this!

As much as I hate to reply to myself :) I've almost got a solution
using Polynomial Rings.
Using lambda, and of course closures, seemed to be the problem. Back
to work!

Hello,
I'm working on a least-squares fit routine and I'm having a bit of
trouble. The method that I'm using involves finding a series of
orthogonal polynomials that have coefficients based on the input data.
Most of the structure is worked out, the polynomials are stored in a
list named phi and

Yann,
If you find any good docs on dsage please let me know.
I'll devote some of my spare time to dsage.
It will be good to get it running in Grid.

Hi vpv,
you can certainly post-process the first option to get an equation system in
the plaintext and key variables alone. You'll need an appropriate term
ordering where each layer's head term is bigger than the previous layer's
head term. You'll also replace the S-Box equations by direct equ
Thanks for your answers, this will probably solve all my problems. And
writing to a file sounds good, since I can always read it's tail and
do whatever I want.

Thanks for your replies, Martin. Yes, indeed I'd like to encrypt
variables rather than constants. Maybe still I can use your first
reply to achieve somehow my goal.
You say that encrypting variables is not supported and should be
added, right? For my own needs I have developed an implementation i
